G
For example, at 16 2/3 - 60 Hz the magnetic trip zone for
the “G” characteristic is 8 to 10 times the rated current of
the specific V-EA (i.e., hold for at least 100ms at 8 x RC,
trip in less than 100ms at 10 x RC). With a 400Hz current,
a magnetic trip at 10 x RC would be greatly delayed
(thermal would likely trip first), as the magnetic trip zone is
now 11.2 to 14 x RC. If a quicker magnetic trip is required
with 400Hz, the “B” or “C” characteristic should be
considered.
The thermal trip is not affected by the frequency of the line
current. The magnetic trip is within the trip zone of the
characteristic curve for frequencies from 16 2/3 to 60Hz. At
lower and higher frequencies, the magnetic trip will be
delayed longer than indicated by the characteristic curve,
roughly as follows:
At 100Hz: Mag. Trip Current = 1.1 x curve current
At 200Hz: Mag. Trip Current = 1.2 x curve current
At 400Hz: Mag. Trip Current = 1.4 x curve current

Mag. Trip Current = 1.5 x curve current
No Load
Resistances listed are “hot” values, as
opposed to cold start values. Operating
voltage drop across the V-EA and power
loss per pole can be approximated with
basic formulas:
V DROP
P LOSS P/P = I
Voltage drops should be reviewed when
V-EAs with high internal resistance are
used (e.g., load voltage minimums).
Power loss should be reviewed when
V-EAs with high rated currents are used
(e.g., enclosure heating).
The listed V-EA internal resistance
values should not be used in
calculations of available short-circuit
current downstream of the V-EA. The
dynamic impedance of the V-EA under
short-circuit conditions can vary
significantly from internal resistance
values in normal operation.
